Permalloys often refer to iron-nickel alloys with a nickel content in the range of 30 to 90%. It is a very widely used soft magnetic alloy. The saturation magnetic induction strength is slightly lower than that of silicon steel, but the permeability is much higher than that of silicon steel, and the iron loss is also lower than that of silicon steel, making it a very good core material.

Permalloy can be divided into 4 categories according to composition: 35%~40% Ni-Fe alloy, 45%~50% Ni-Fe alloy, 50%~65% Ni-Fe alloy and 70%~81% Ni-Fe alloy . Each type can be made into materials with circular hysteresis loop, rectangular hysteresis loop or flat hysteresis loop.

The iron core made of nanocrystalline ribbon has high magnetic permeability and low coercivity. It is especially sensitive to leakage current in the initial stage of magnetization. The leakage switch made with this iron core has a small operating current. At the same time, it has good resistance to high current impact. Because the nanocrystal um is an order of magnitude higher than that of permalloy and has high sensitivity, the number of primary winding turns can be reduced for leakage switches that require the same sensitivity, thereby reducing the volume of the leakage switch accordingly. It not only saves costs but also meets technical requirements.

Products can be customised It is mainly used for power taking, energy conversion, power measurement, leakage protection, etc. Such as: various types of different levels of current transformers, power transformers, current sensors, etc. used in the power system.

Common mode choke, abbreviated as CMC, also known as common mode choke, is commonly used in switching power supply to filter common mode EMI signal. In the circuit design, the common mode inductor also plays the role of EMI filtering. Common mode inductance is used to make differential mode signal (required signal) pass through, while common mode signal (noise) cannot pass through. It can be used in electronic products, personal computers, switching power supply and so on.

Products can be customised The magnetic metal cut core manufacturing process is designed to produce transformer cores with the lowest possible losses and magnetizing currents. We have silicon steel, permalloy, nanocrystalline, amorphous and other materials to choose from to meet strict specifications such as extremely low loss and high pulse permeability.

Products can be customised Magnetic Metals tape wound cut core manufacturing processes are designed to produce transformer cores having the lowest possible losses and magnetizing currents. Where required, special selection of steel is made to meet exacting specifications for very low loss, high pulse permeability, etc.  As a result, the assembled cores exhibit exceptionally low hum and low exciting current.

Hemei Electronics is a domestic manufacturer specializing in the research, design and production of power supply current transformers, split core current transformers, clamp-type current transformers, high-precision current transformers and miniature voltage transformers. Measures AC current from 1A to 5000A with outputs of 0.333V, mA, 1A and 5A.

Amorphous alloy current transformer uses amorphous alloy material as the core material, which better solves the problems existing in the traditional current transformer. Amorphous alloy has the advantages of low hysteresis, low loss and high saturation magnetic induction strength, which can effectively improve the measurement accuracy. In addition, amorphous alloy current transformer has the characteristics of small size, light weight, flexible installation, etc., which is convenient for the installation and use of equipment.

The split core current transformer are designed for fast and easy installation.The CTs are ideal for installation on existing electrical cables by clamping on the conductor.This method permits a safer,easy and portable current measurement.An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary.

Choke coil, also known as inductor coil, reactance coil or impedance coil, is an electronic component that plays an important role in controlling the magnitude and phase of current in an AC circuit. It can isolate high frequency currents, generate inertial potentials, and limit the passage of current, thus realizing the control of current in the circuit.
